Guatemalan officials told the AP that there were reports of power outages and rock slides on some roadways in the affected area. The country's newspaper, Prensa Libre, posted photos of huge cracks in the facades of buildings in San Marcos. One even partially collapsed, the AP noted.

"This quake was pretty strong," Rivera told Reuters. "Families in the area are really scared because of the whole experience of November 2012. There are houses destroyed."

Guatemalan fire services spokesman Raul Hernandez told the news agency that two died in San Rafael Pie de la Cuesta in San Marcos. Twelve people were taken to a hospital to receive treatment and 50 houses were evacuated in the region.

"The whole San Marcos region is pretty affected," Sergio Vasquez, another spokesman for fire services, said.

Mexican news media reported that the earthquake was strongly felt in the states of Chiapas and Tabasco, according to USA Today. Another man reportedly died in Huixtla when he was hit by a collapsed wall, according to the AP.

"I thought the house was going to collapse," Claudia Gonzales, 32, told the AP after she ran into the street with her 1-year-old daughter in Comitan.

Reuters reported that that the earthquake was centered about 22 miles west-southwest of Tapachula, in the Mexican state of Chiapas at a depth of about 47 miles, per the U.S. Geological Survey.

Omar Santos, a city employee in Tapachula, near the earthquake's epicenter, told reporters that "buildings were moving, windows broke in some houses and businesses, and people ran through the streets in the dark."
